NextDNS CLI problem

I installed the latest version of the CLI on my ax86 and I’m noticing the router has started to throw unassigned buffer errors and other issues. Then today the CLI stopped working, and had to be reinstalled.

Are there any known issues with NextDNS and Merlin 386.5?

No issues at all here with NextDNS CLI on my AX86U with 386.5.
Maybe you can publish your CLI-config (with your settings-ID masked) and a piece from your system-logs when it happens? Are you running lots of other add-ons so free RAM could be the issue?! I remember the NextDNS team recommended setting the cache to 1 MB or disable it for testing.

The config looks fine and plenty of free RAM. Any clues in the log when it happens?!
Have you tried posting in the NextDNS Support Forum where the NextDNS team hangs around: https://help.nextdns.io/

Seems like your JFFS-partition is corrupt. I would try "Format JFFS partition at next boot" under Administration->System, but notice that you will loose settings/add-ons stored there.
The other error with "bcm63xx_nand" seems related to Broadcom and found some other threads with similar errors.
I personally would probably do a full nuke/reset (following L&LD guidelines) if the problems persists, since 386.5 is a quite big update with new GPL 386.46xxx.
